V raziskavi smo želeli ugotoviti ali uporaba oljčnih listov in tropin v krmnih mešanicah vpliva na proizvodne lastnosti in na mineralizacijo kosti pitovnih piščancev. V poskus smo vključili 120 en dan starih pitovnih piščancev ross 308 in jih do 21. dneva krmili s krmno mešanico štarter. Po 21. dnevu smo živali krmili s krmno mešanico finišer in jih razdelili na 5 poskusnih skupin (24 živali na skupino): kontrolna skupina brez dodanih oljčnih listov in tropin v krmni mešanici (FIN KONT), skupina z dodatkom 5 % oljčnih listov (FIN+5 % listi), skupina z dodatkom 10 % oljčnih listov (FIN+10 % listi), skupina z dodatkom 5 % oljčnih tropin (FIN+5 % tropine) in skupina z dodatkom 10 % oljčnih tropin (FIN+10 % tropine) v kilogramu krmne mešanice finišer. Po končanem poskusu smo živali žrtvovali (5 živali na skupino) in jim odvzeli vzorce kosti (stegnenica, golenica, nadlahtnica). Kostem smo izmerili fizikalne lastnosti ter vsebnost mineralov v surovem pepelu (SP). Uporaba oljčnih listov ali oljčnih tropin ni vplivala na proizvodne lastnosti, fizikalne lastnosti kosti in vsebnost SP. V vsebnosti mineralov v kosteh smo statistične razlike izmerili pri vsebnosti Mg v stegnenici v skupini FIN+ 10 % listi, v vsebnosti Cu v stegnenici v skupini FIN+5 % listi, v vsebnosti Zn v golenici v skupini FIN+10 % oljčnih listov in FIN+10 % oljčnih tropin in v vsebnosti Cu v nadlahtnici v skupini FIN+5 % oljčnih listov in FIN+10 % oljčnih listov v primerjavi s kontrolno skupino. Vsebnost mineralov se v kosteh ni zmanjšala. Na podlagi rezultatov lahko oljčne liste in tropine uporabljamo kot varno in naravno krmilo za pitovne piščance v koncentracijah 5 in 10 %.

• Title: Effect of olive leaves and olive pulp in feed mixed on bone mineralisation of broiler chickens

Abstract

The aim of the research was to determine if the use of olive leaves and olive pulp in feed mixtures affects performance traits and bone mineralisation in broiler chickens. 120 one-day-old Ross 308 broiler chickens were included in the experiment. They were fed with the feed mixture starter until day 21. After day 21, the animals were fed with the feed mixture finisher and divided into five experimental groups (24 animals per group in total): the control group without olive leaves and pulp mixed in the feed mixture (FIN CONT), the group with 5% of olive leaves (FIN+5 % leaves), the group with 10% of olive leaves (FIN+10% leaves), the group with 5% of olive pulp (FIN+5% pulp) and the group with 10% of olive pulp (FIN+10% pulp) per kilogram of feed mixture. After the nutritional experiment, five animals from each replication were randomly selected and slaughtered. A sample of three bones (femur, tibia, humerus) was taken from each animal. The physical properties and the mineral content in ash were measured in the laboratory. The use of olive leaves and olive pulp did not affect performance traits, physical properties and ash contents. In comparison to the control group, the statistical differences in mineral content were measured in Mg content in femur in the FIN+10% leaves group, Cu content in femur in the FIN+5% leaves group, Zn content in tibia in FIN+10% leaves and FIN+10% pulp groups and Cu content in humerus in FIN+5 % leaves and FIN+10% leaves groups. The mineral content in bones did not decrease. Based on the results, olive leaves and pulp can be used as safe and natural feed ingredients for broiler chickens in 5 and 10% concentrations.
